2 What to know before using

If you are about to start a drug therapy, the risk-benefit ratio of taking the drug should be considered carefully. The suitable drug therapy is chosen by the doctor with active participation of the patient.

There are some important factors such as:

  • drug interactions,
  • patient’s condition,
  • prevalence of metabolic impairments,
  • hypersensitivity reactions etc. which may alter the desired therapeutic effects of such medications.

Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects. The use of anthrax vaccine is contraindicated in anthrax infection, debilitated patients, and in those who are allergic to the component of this vaccine. Further, you must inform your doctor if you have had any allergic reaction to any medicine.

Certain drugs should not be used concurrently with such medications. It is always recommended to consult with your doctor if you are in need of some other medications or even any over-the-counter medicine for another health problem in order to avoid unwanted toxic effects.

Studies in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy in a life threatening situation or a serious disease may outweigh the potential risk. Further, studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
